IMPROVEMENT IN HEATERS FOR WASH-STANDS.

Specification forming part of Letters Patent No. 1 54,392, dated August25, 1874; application filed May 11, 874.

To all whom it may concern:

Be it known that we, WILLIAM HERLEHY and RICHARD J OHNSON, of Pittsburg,in the county of Allegheny and State of Pennsylvania, have invented anew and useful means of Warming and keeping warm a supply of water, suchas may be required in public and private buildings, bed-rooms, &c., ofwhich the following is a specification:

Our invention will be-readily understood from the following description,taken in connection with the accompanying drawing, wherein-- p Figure 1represents a perspective view of a wash-stand, having its front doorsremoved to exhibit the application of our invention. Fig. 2 represents alongitudinal section of the boiler or water-heating apparatus, and aportion of its attachments; Fig. 3, a transverse section of the same.

The object of our invention is to furnish such wash-stands as areusually connected to a street-main with a means of warming the in-goingwater on its way to the basin, and which is accomplished by a burningjet of gas acting on a small boiler or tank arranged within the body ofthe wash-stand, the several parts being so connected and made to operatewith respect to each other as that hot or cold water, or a mixture ofthe same, may be drawn those in ordinary use. At the opposite side ofthe basin is arranged a similar faucet, F, so connected to a pipe, H,extending down into the tank O, as that hot water will flow through itwhen its faucet is swung over the basin.

To generate heat, and thereby warm the water in the tank, we haveconstructed it with a large horizontal flue, K, in which is arranged agas-pipe, L, furnished with burners e e 0, over which is placed a finewire-gauze, a, which creates a smokeless flame, which, although small,will be found sufficient to heat and keep hot the water, the pressure ofgas being regulated, &c., by means of an ordinary key, f.

To provide against any explosion possible on the undue accumulation ofsteam, we have attached to the tank a safety-valve, I, so contrived asto allow such steam to escape through aconnecting branch, J, into thewastepipe m, just below its bend or trap.

For the purpose of keeping up a lively and continuous circulation of thewater in the tank, we have connected its opposite ends by means ofS-shaped pipesg g, that extend into and through the flue K above thegas-flame, which arrangement is found to answer the 0bjeot required.

We claim- A new and improved heater-for wash-stands, consisting of thesteam-tight boiler 0, having a longitudinal open-ended fi-ue, K, incombination with the S-shaped circulating-tubes g g, inlet-pipe E, andoutlet-pipe H, as and for the purposes set forth.
